Initial analysis

The 4-unit, 2-story multi-family residential building at 561 41st Ave in the Outer Richmond district, owned by Mar Jack G & Pauline L, was constructed in 1954 and has undergone several maintenance and repair activities over the years. The property's maintenance history shows basic infrastructure upgrades, including reroofing completed in 1992 and an electrical service upgrade to 150 amps in 2010. Of particular concern are the building's recent structural and safety issues, notably a significant balcony repair situation in May 2021, where concerns were raised about wooden slabs on the front porch balcony, including loose and cracked slabs potentially affected by dry rot. While initial repair attempts involved only temporary fixes, subsequent work partially addressed the issue by securing the slabs, though the repairs appear to have been incomplete.

The building has experienced various other maintenance issues, including plumbing problems reported in January 2019. Historical records show routine housing inspections in 2003, which were promptly resolved. Recent external issues primarily relate to parking concerns in the vicinity of the building, with multiple parking enforcement calls documented between 2018 and 2024, though these do not directly impact the building's habitability. Several noise complaints were reported in 2018, including mechanical equipment noise and vehicle repair sounds, but these were addressed through normal channels. The property has had limited documented housing code violations or serious complaints, with most issues appearing to be routine maintenance matters rather than significant habitability concerns.

Risk rating

How 561 41St Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
